I've decided on the other way round. Hooks on the Board.
Reasons: My Board is usually full of Pedals, so there's not much chance of catching stuff.
Also, i am not in the habit of placing it face down on the carpet. I am, however in the habit of placing pedals that are not on the board on the carpet occasionally.
And, on top of that, the only pedal i bought used had the loop side velcro on the bottom.
